PROCEDURE FOR REFINEMENT OF IRON ORE FROM ARSENIC AND PHOSPHORUS
FIELD: metallurgy. ^ SUBSTANCE: procedure consists in crumbling ore, in its mixing with carbon reducer and in mixture sintering. Also, before sintering ore is additionally mixed with carbonate slime; mixture is sintered in oxygen containing medium. Upon sintering arsenic and phosphorus are leached w...

| description | FIELD: metallurgy. ^ SUBSTANCE: procedure consists in crumbling ore, in its mixing with carbon reducer and in mixture sintering. Also, before sintering ore is additionally mixed with carbonate slime; mixture is sintered in oxygen containing medium. Upon sintering arsenic and phosphorus are leached with solution of sodium hydroxide and simultaneously are subjected to wet magnetic concentration. ^ EFFECT: increased contents of iron at low contents of arsenic and phosphorus. ^ 9 cl, 2 tbl, 1 dwg, 11 ex
Изобретение относится к способу очистки железной руды от мышьяка и фосфора. Способ включает измельчение руды, ее смешивание с углеродным восстановителем и обжиг смеси. При этом перед обжигом руду дополнительно смешивают с карбонатным шламом и обжиг смеси проводят в кислородсодержащей среде. После обжига проводят выщелачивание мышьяка и фосфора раствором гидроксида натрия с одновременным мокрым магнитным обогащением. Технический результат заключается в увеличении содержания железа при низком содержании мышьяка и фосфора. 8 з.п. ф-лы, 2 табл., 1 ил. |
